From the WSJ--estimated worldwide shale gas plays. Hopefully the link will stay up. Of special note take a look at Argentina which has the 3rd largest footprint behind China and the US. Hopefully the recently held meeting at the US Embassy will jump start the industry down that way. Just in case the image is no longer available China is listed as having 1,275 trillion cubic feet (although mostly very difficult to tap and without infrastructure,) the US 862 and Argentina at 774.
Looks like the Image link isn't going to work, but in addition to the above this paragraph about Argentina from the "Global Gas Push Stalls" would certainly give one pause for reflection prior to committing resources there:
Argentina recently nationalized the assets of a Spanish company that discovered an enormous shale deposit there that is estimated to hold nearly one billion barrels of oil. This has chilled outside investment, which already suffered from rules that made it difficult to import needed technology and export potential profits. Houston-based Apache Corp., APA -0.07% which holds rights to drill in 450,000 acres of Argentine shale, says it can cost twice as much to drill a well there as the U.S., and then two to four times as much to frack the well so it can begin producing.
This should also "chill" Capstone into a take a slow and careful stance concerning doing business there. I would think payment in full prior to any product leaving the shipping dock would ice the cake quite well.
